My invention relates to H92l-3iii and; traction devices for vehicles sueh as heavy motor trucks having wheels provided with dual elastic tires and. for iteohjeei the production of a device of? this chmecter which will not slip on ilie surf-see of the tires, nor on the roeilheii, one} which will produce only a minimum of uneven. oi shah tering action when the vehicle proi Cleo the device runs over fisolid peven This application constitu my prior application Se filed December 2 53,. Hi issuerl as Patentlg'fiil f? her 16, 1915.

The best form of eppaz'ems at present. known to me emhoclying my invention is illustrated in ihe accompanying sheet of drawings, in whieh- Figure 1 isev plan View of e seeiion of the Wheel face with one form of my invention applied thereto. Fig. 2- is a vertical section. of the wheel taken on line 2-2 of Fig. 1, the non-skid device being shown. in full lines, with parts broken away, Fig. 3 is a cross section taken on the irregular line 3-3 of Fig. 1.

Throughoutthe drawings like reference characters indie-ate like part-s.

1, is the wheel provided with dual eiestie tires 2, 2, usually made of me. rubber.

The non-skid device consists of a series of shoes held together by flexible chains aml having extensions or Wings, Whieh overlie the faces of the elastic tires, the eonnee 'ng chains lying in the groove between the tires The shoe 3, has diagonally exoendmo 'ings 33, 33, Which overlie the faces of the tires '2, 2. The central portion of the shoe has a depressed or gTooved part 13, and pro jecting ears 25 23 to which the chain see ions may he conneoi-ei While any desired of so neeting means may he emgplo ve zl I sew n a series of fizz-t links 6, 6, elieroaeing Key 9 1916.

A non-skid traction device for wheel: provided with dual elastic tires having in combination a series of shoes provided with oppositely extending wings comprising flat, elongated plate-like formations adapted to rest on the surfaces of the tires and provided with external, raised ribs extending lengthwise thereof, the inner ends of said ribs being separated by an exterior groove extending transversely thereto, pairs of parallel lugs extending from either side of each shoe so located that the spaces between the lugs of each pair form extensions of the before mentioned groove, and connecting members pivoted between said lugs, the two rib portions of each shoe being out of line one with the other.

/ 3. A shoe for use in non-skid devices for wheels provided with dual elastic tires provided with oppositely extending wings comprising flat, elongated plate-like formations adapted to rest on the surfaces of the tires and provided with external, raised ribs extending lengthwise thereof, the inner ends of said ribs being separated by a groove in the exterior surface of the shoe running transversely of the ribs, and pairs of parallel lugs extending from either side of the shoe perforated to serve as attachments to connecting means, said lugs being so located that the spaces between the members of each pair form extensions of the before mentioned groove.
